This invention relates to vacuum or suction cleaners, and it has to do especially with a bag or dirt-receiving receptacle for such a cleaner; The

of-clot particles of dirtor dust, but which was sufficiently porous to permit the air. to pass therethrough. This sort of bag has to be cleaned out every once in awhile, and after a period of time fine particles ofdirt collect in the interstices ofthe cloth, and thus there is an interference in the passage'of the air through the cloth. This cuts down the draft of air and accordinglyreduces the efiiciency of the machine.

It has been proposed to provide cheap replaceable bags made of porous paper which,

lpractice has been to make such a bag -after a considerable quantity of dirtis col- 2o lected, is to be thrown away and a new bag substituted. This proposal contemplated placing of the paper bag within a cloth ex terior bag for lending some support for the paper bag and for protecting the same. It has been found quite diflicult to place the paper bag within the .cloth bag so that there are no creases or folds in the. paper bag, and so that a dust-tight joint is provided between the paper bag and the dischar e outlet of the vacuum machine. Some 0 these cloth exterior bags have'been split down the side and provided with separable fasteners so that the same can be opened up. However, the fasteners aresubject to deterioration and should a fastener break, thebag'open's so that'the paper ba becomes exposed. Inasmuch as the paperiags are relatively fragile, the pressure of air within the .same, while the machine is operating, is very liable to break the bag openwith the result that dirt particles are discharged over the room.

The present invention contemplates a rigid exterior container for the fragile replaceable inner containers. This exterior container is advantageously madeof a wire screen or mesh, and preferably it is of the same size as the contained replaceable bag when the same is expanded 'b a" draft of air. This rigid exterior container is preferably attached to 60 the handle of the cleaner so that it will not having a texture to retain the. fine the bag 5. The bag 5 may be provided with swing with respect thereto, thus facilitating the twisting and turning movements necessary in the operation of the vacuum cleaner.

In the accompanying drawings:

Fig. 1 is a side elevation of a vacuum cleaner equipped with a dirtcontainer constructed in accordance with the invention.

Fig. 2 is an end elevation of a container showing the end which is attached directly to the vacuum machine.

Fig. 3 is a sectional view taken on line 33 of Fig. 2. I

F ig. 4 is a section taken on line 4-4 of Fig. 2 illustrating-also the outlet part of the I vacuum machine. i 86.

Fig. 5 is a perspective view illustrating the paper bag about to be attached to the removable head of the exterior. container.

In Fig. 1 there is shown a vacuum cleaner provided with a suitable motor 1, handle 2, lo and'mouth portion 3. The motor in operationsucks air through the mouth portion and discharges the same through the discharge outlet 4.

The air, together with the particles of dirt carried with it are discharged from the outlet 4 into a bag or container. The container of the present invention consists of a rigid. outer member 5 preferably of wire mesh or screen. This screenmay be provided with a number of reinforcements inthe nature of metallic bands 6. One end of the container5 is removable to permit the insertion of a relatively cheap replaceable inner bag member such as a bag of porous paper. This removable head is shown in Fig. 2. and is referenced 10. The-head may be vprovided with a rotatable locking member 11 which engages 1 under clips 12 to lock the same to the end of apertured ears 13 for fitting over studs 14 (Fig. 4) on the vacuum machine proper.

This head also h s an opening fitted with a suitable attaching member 15.- -This attaching member 15 maybe in the form'of a '5 rubber nipple. As viewed in Fig. 5, the paper bag 16 is provided with an inletopem'ng 17 which may be advantageously of relatively non-expansible paper. It may also be provided with tabs 18'which'may'be grasped in order to pull the inlet member 17 over the the inlet opening 17.

After the paper bag has been pulled upover the nipple 15 the same is inserted'in the screen container 5 and the head 10 secured in place by means of the locking member 11. The nipple 15 is now pushed downover the discharge member 4 and it will be noted by reference to Fig. 4 that this discharge member has exterior walls which converge toward its outer end so that when the nipple is placed over the member 4 the same is exanded to form a tight joint with the paper ag. v

In placing the bag on the machine the studs 14 pass through the ears 13 and a spring clip 20 may be utilized which snaps over one of the ears to hold the bag in place. The upper end of the bag may be held to the handle by a hook-and-eye engagement, as shown at 21 in Fig. 1.

Thus, it will be seen that it is a very simple matter to remove the receiving receptacle in its entirety, and replace the partially filled inner paper bag with a new one. Preferably the shape of the interior paper bag, when expanded, is substantially that of the exterior rigid supporting receiver member. The particular shape and construction ofthe receiving bag may be .varied. 'Also, the manner in which the bag is connected to the vacuum machine proper and the'structural features of the removable head for the bagmay be changed without departing from the spirit of the invention. This wire mesh or screen member can be used with the screening exposed to view, but it may be covered with suitable cloth which may add to the appearance, if the same be desirable.

The manner inwhich the connection is established between the paper bag and the vacuum machine proper forms the, subject matter of a separate application, and while this construction is preferred, other forms of connections may be used with the wire mesh outer container.

I claim: I In a vacuum cleaner, the combination of a vacuum cleaner body, a handle member rigid with the body, an outlet spout on the body, a bag of paper or the like designed to be thrownaway when filled or partially filled with dust or the like, a tubular inlet portion" on the bag, a substantially rigid outer container for the bag constructed to let air pass therethrough, a detachable end closure atone end of the bag having an aperture, means on said closure associated with said aperture for operatively receiving the tubular inlet of the bag, said bag being adapted to be placed in .the outer container after being operatively associated with said means, means for holdf ing the closure on the end of the outer conand means for holding the outer container ri 'd with the handle and body member.
